The liquid passagesin these nozzles Fig. 1 is an elevation of one form of the immay be ofvarious diameters, and are usually conproved implement, loolnng towardthe liquid flow siderably smaller than the passage 15 in the supcontrollever and toward the end of the liquid port 10.

)0 supply' reservoir; The end of the cylinder or reservoir 12 which Fig.2 is a central longitudinal section through communicates with thepassage 15 of the supthe implement and supply reservoir of Fig. 1, theport 10, may be provided with a removable closure section being takenalong the line 22 of 1; 27 for filling the reservoir displacementchamber Fig. 3 is an enlarged longitudinal section with liquid paint 14or the like. The opposite 55 through the flow control portion of theimpleend of the reservoir 12 is provided with a removable cap 28 throughwhich the plunger rod 29 extends, and a helical-spiral compressionspring surrounds the rod 29 and coacts with the cap 28 and plunger 13.The plunger 13 is furthermore provided with a cup-shaped packing 31which is held in place by a retainer 32 and nut 33, and prevents paint14 from escaping past the plunger 13. When the reservoir 12 is beingfilled with paint 14, the plunger 13 is withdrawn by hand with the aidof the rod 29, to compress the spring 30, and this spring 30subsequently functions to urge the plunger 13 against the paint 14confined within the reservoir, upon release of the rod 29. If thecontrol valve 16 is then opened, the spring 30 coacting with the plunger13 will force paint from the reservoir 12 through the passage 15 andnozzle 11 until the supply is entirely deleted or exhausted.

The mode of utilizing the implement shown in Figs. 1 to 4 inclusive,should be clearly apparent from the foregoing description. When thereservoir 12 has been properly charged with paint 14 and the closure 27has been applied, the implement may be manipulated like an ordinarypencil or brush to produce lines of paint flowing from the nozzle 11. Afinger of the operator may be applied to the control lever 19 toregulate the flow of paint, and the set screw 22 serves to vary thedegree of opening of the passage 15. As the paint 14 is discharged fromthe reservoir 12 by the spring 30, the plunger 13 gradually approachesthe closure 27 until the paint supply is entirely exhausted. The variousparts may be readily removed for inspection and cleaning, by merelyreleasing the cap 28 and plug 18, and the implement is so compact thatit can be carried in an ordinary pocket.

Referring specifically to the embodiment of the invention shown in Fig.5, the implement again comprises a support 40, a nozzle 11 secured toone end of the support by means of a carrier 26 and lock nut 25, areservoir 42 connected to the opposite end of the support by means of ahose 41, and a plunger 43 movable within the reservoir 42 by means of ahelical-spiral spring 44. The

support 40 difiers from the support 10 previously described, only inthat it is flexibly connected to the supply reservoir 42 by the hose 41,instead of being rigidly attached to the reservoir. The

support 40 is provided with a control valve 16 identical with thatpreviously described, and the nozzle 11 and its attachment are also thesame as those heretofore described.

The upper cap 45 of the receiver 42 is provided with an eye 46 forsuspending the same from the belt of an operator or from a trolley, andthis cap 45 is moreover provided with a closure 27 for supplying paint14 to the reservoir 42. The lower cap 47 against which the spring 44reacts, has a central bushing 48 with which the hollow plunger rod 49coacts. The plunger 43 as in the case previously described, is providedwith a cupshaped packing 31 held in place by a retainer 32 and a nut 33,and the plunger rod 49 has a through passage 50 therein, the upper endof which communicates with the paint supply confined within thereservoir 42, and the lower end of which communicates with the hose 41through a nipple 51 attached to the lower end of the plunger 49.

The implement of Fig. 5 enables the storage of a greater supply of paint14, than is possible with the pocket implement previously described, byvirtue of the fact that a reservoir 42 of any desired capacity may beutilized. The hose 41 may be of any desired length and is suflicientlyflexible so as not to interfere with the free movement of the support 40and nozzle 11 during normal use of the implement. In the implement ofFig. 5, the rate of flow of the paint 14 from the reservoir 42 will besubstantially constant because of the vertical disposition of thereservoir, and as the paint supply is diminished, the spring 44 willexpand and the difference in expansive effort of the spring as its limitof expansion is reached, will be compensated for by the diminishingweight of the paint supply.

From the foregoing description it will be apparent that the presentimprovement provides a marking implement which is extremely simple andcompact in construction, which is highly efficient in operation, and allparts of which are readily accessible for cleaning. The delivery ofpaint from the supply reservoir may be readily and accurately controlledby manipulating the control lever 19 and by adjusting the set screw 22,and the nozzle 11 may be conveniently replaced by any other suitabletype of nozzle or brush. The supply of paint 14 may be readilyreplenished with the aid of the plunger rod, and the spring coactingwith the plunger effectively maintains the liquid hermetically sealedand in constant readiness of use.

It should be understood that it is not desired to limit the invention tothe exact details of construction herein shown and described, forvarious modifications within the scope of the claims may occur topersons skilled in the art.
